elastomers, Plastics & comPosites

Complex requirements require integrated solutions. That is particularly true in growth markets such as the composites industry. You can benefit from the pooled expertise of our composite experts and from new technologies for challenging composites applications. Whatever your needs – be they immaculate surfaces combined with zero shrinkage and high mechanical strength; control of the flow behavior of laminating resins and gel coats; or you want scratchproof composite stone, or effective control over curing – the correct additives will ensure you achieve just what you want. WACKER offers you a high-performance portfolio for optimum combinations whatev-er the application – bulk molding com-pound, pultrusion, resin transfer molding, sheet molding compound and hand lay-up or spray-up.

Composite Products

WACKER acetylacetone is used as a copro-moter to maximize the quality and yield of complex curing processes. ELASTOSIL®_C

permits innovative silicone system solutions – such as dimensionally accurate produc-tion of reusable vacuum bags. They can achieve huge savings compared to dispos-able vacuum film. In challenging materials such as composite stone, GENIOSIL®

si-lanes act as coupling agents, enabling the organic resin to chemically bond to the inor-ganic mineral. For hand lay-up of compo-sites, HDK®_{pyrogenic silica provides expert}

control of flow behavior. VINNAPAS®_solid

resins are low-profile additives for compo-site parts providing a constant high product quality with first-class smooth and glossy surfaces and no shrinkage.

Concrete Castings

Concrete castings that remain permanently elegant and robust must be cast using moldmaking materials that are alkali resistant with long-term stability, and can faithfully reproduce even and uneven surfaces and undercuts. Molds made with addition-curing ELASTOSIL®_{M silicones from}

WACKER are ideal for a wide range of applications – figurines and statues as well as the indus-trial production of composite-stone facings.

Moldmaking for

Food Contact

The prime consideration regard-ing moldmakregard-ing materials for foodstuffs is that they comply with legal requirements. Other im-portant concerns are neutral taste, permanent stability and im-parting a faithfully reproducible shape to the most diverse of food products. These advantages are exhibited by special addition-cur-ing ELASTOSIL®_{M molding}

com-pounds, which can be used for the lifelike replication of foods.

For Architectural Design

and Decoration

In architecture, a striking, integrat-ed idea is creatintegrat-ed through a skilful combination of structural design, materials and visual effects. This makes tough demands on the re-production technology. Success depends more than ever on faithful replication of the original model – not to mention molds with good long-term stability and resistance to different molding materials. ELASTOSIL®_{M moldmaking}

com-pounds do all this, while also offer-ing architects many other product advantages for the customized reproduction of classical elements or special effects.

Reproduction at its Best

Whether for individual works of craftsmanship, functional prototyping or industrial mass production – first-class results in modern moldmaking demand faithful reproduction, outstanding release properties and high resistance.

Design

While there are potentially infinite design possibilities, there are se-rious constraints on the repro-duction of design elements – un-less you use the right products, of course. With ELASTOSIL®_M

condensation-curing RTV-2 sili-cone rubber grades, molds can be produced quickly and easily. Their functional properties allow the original to be replicated in faithful detail, and they offer the added benefit of excellent resis-tance to different reproduction materials.

Industrial Production

Industrial mass production re-quires materials with extremely high product reliability, perma-nent durability and efficient pro-cessability – all these require-ments are met by ELASTOSIL®_M

moldmaking compounds. WACKER’s RTV-2 silicone rubber grades exhibit excellent mechani-cal properties such as tear resis-tance and tensile strength. They are also available in different hardnesses, ensuring that every mold has just the right flexibility.

Rapid Prototyping

When prototypes are needed, a mold must be produced quickly. This requires moldmaking materi-als with outstanding inherent release properties, excellent flow and good transparency. WACKER’s ELASTOSIL®_M

addition-curing RTV-2 silicone rubber grades ensure success in these challenging applications, and permit functional as well as economic advantages in this application field.

Catalysis

Automotive and mechanical engineering, packaging technology, building construc-tion, the textiles, toy and cosmetics industries – hardly any modern industrial application would be conceivable without the use of polypropylene (PP). There are good reasons why, since PP provides plas-tics manufacturers with a wide range of properties. Important ingredients in the chemical conception of this polymer are donor silanes from WACKER. The produc-tion of PP by olefin polymerizaproduc-tion is of enormous technical and economic impor-tance. Donor silanes are used as cocata-lysts in this case, ensuring a high content of isotactic polymer, controlling the mole-cular weight and determining the quality of the end polymer.

Applications
